I don't know about the '96 vans, but the later ones were fitted with after market A/C kit, presumeably because the OE option was too expensive.
This is the main reason why the dealer's parts manual cannot specify the correct belt. Take your sample belt to any industrial supply store & they should be able to identify & supply one.
As Seano has said don't leave it off even if the compressor is the only accessory driven by it, as lack of use will finish it off. I make a practice of running mine for a few minutes everytime I drive it to keep the oil splashing over the seal.
What petrol engine do you have, the 4 or 5cyl?

Understand how it works, troubleshoot logically BEFORE replacing parts.
